Hartz Plus Killed my Best Friend

Last week I bought Hartz Plus, for my 2 cats. They were born 9-17-2001. On Sunday 8-17-2008 6:28 am one of them died from acute respiratory arrest after applying the Hartz Plus flea/tick medicine AS DIRECTED 2 days prior. She was ok at first and it seemed to be working. Then the next day she was a little lethargic and not eating as much, after watching her closely she began to return to her normal self. Then next evening the suddenly fell quite ill and wouldn’t eat or drink. all she could do was lay there. and groan. She was promptly bathed and bottle fed water and liquid food. Once again her condition improved. My wife and I took shifts watching her over the night so we could take her to the vet as soon as they opened. And all was well until about 6:00am. She began to have difficulty breathing. Without hesitation I rushed her to the emergency animal clinic as fast as I could. Speeding, not coming to complete stops, I was lucky to not get pulled over. I arrived at the emergency clinic 6:26 and she was admitted right away. we made it to about as far as the table when she started to have violent convulsions and making the worst wailing sound I have ever heard. She was rushed to the operating table immediately and died within seconds before much could be done to save her. Unfortunately the only bit of relief i could be given was an apology and a statement “We have had increasing amounts of Hartz related deaths”. Then the doctor didn’t even charge me for the services, which is very unlike the emergency animal clinic. They normally charge $96 just for walking in, which is a major detourant for those of us with low budgets, another reason we purchased Hartz, as apposed to Frontline as we would usually get. After this, I will NEVER use Hartz products, EVER AGAIN.

Seargent’s Silver NEVER USE

I have a beautiful 7 month old toy poodle and I almost lost him today because of the allergic reaction to Seargent’s Silver.  I have always used Frontline with no problems but unfortunately he was due for another application and I didn’t have the Frontline.  I decided to try one of the less expensive brands just to see. A half hour after I applied it he started running in circles crying and itching.  I immediately bathed him and then called my vet.  They said bath him in Dawn 3 times.  After the second bath I rushed him to my vet.  He gave him a shot of prednisone, benadryl and washed him again in a special shampoo.  I have to administer 2 more doses of oral prednisone tonight and in morning. I brought him home and he was still itching and crying but now he is calming down in his bed but still itching some but at least he is not crying.  The vet said to keep a close eye and any changes to call immediately.  We think he will be OK but I will NEVER use that product again and Please don’t anyone else use it either.  I feel terrible because I used the cheap stuff.  NEVER AGAIN!  I don’t care about the vet bill just my precious baby.

HartzVictims.org saved my cats

Our three cats came down with fleas this August 17 and in previous years we had used Frontline and it worked well.  I sent my husband out for Advantage today at Pet Smart since there have been recent complaints of this years Frontline batch not working. I had one Frontline left from last year so I put it on the cat that I noticed fleas on and waited for hubby to return with meds to put on the other 2 before they became infested. He came home with this Hartz Ultra Guard Pro instead, probably since it was cheaper.  I was wary of this wroduct as I had not used Hartz brand before, so I Googled the product and found BAD reviews, 1 star on all pet product sites. Then I found your site and felt  ILL  .  I was that close to putting it on 2 of my precious babies. I have no doubt that it would have had extremely adverse reactions. I was just one of the lucky ones who found your website and took heed.

Tomorrow the Hartz is being returned….along with a printed copy of ALL of these posted warnings, to Pet Smart, to the manager. I am also phoning Hartz and posting as many links as I can to direct people to your website. Thanks to you MY cats are safe……I will help spread the word.

Sargeant Flea & Tick Spray Killed My Two Cats


Gizmo is dead…and Mieko is dying…(update is now dead too)…they somehow were poisoned … I’m certain it was the flea spray..I sprayed them both two nights before at separate times hours apart because their battle with fleas was severe…Please warn any cat owners you know about Hartz/Seargents flea sprays they are deadly and should be banned…they contain deadly toxic chemicals and have to be administered to a “T” or it will certainly make your cat deathly ill or kill your pet which is more likely depending on the size of the cat…and that goes for dogs as well…I feel the company cares little about the wellbeing of animals otherwise there wouldn’t be such a product…it is not completely safe to administer…my cats are dying proof…after I administered the flea spray my female Black Point Himalayan cat fought profusely until she ran off hiding for two days… when I came home later in the evening around 9:30 pm i opened the front door to find her dead with my other cat by her side I think he found her and brought her out from where she was hiding…he wouldn’t leave her side…next thing I know he’s getting wobbly on his feet and he was lifeless before I knew it…I called the vets (but because I had no means to pay for it due to my limited pension after suffering a massive heart attack two years ago)…at that point was offered no help…one vet had a party to go to and was late…I think that was despicable and heartless…all the vets offices were closed for the weekend…So, I looked up information on the internet only to find others encountering the same problem…I finally took it upon myself to hopefully find a way to keep him alive…I gave him first off some water via syringe because he would’nt eat or drink so i force fed him as well as a syringe of milk mixed with egg  and gave him a bath with polmolive soap and wrapped him up and he lived through the night as i stayed by his side to maintain him all night…he seemed to be bouncing back then suddenly went lifeless again…I crumbled up some cat kibble  to a fine dust and mixed it with the milk and egg…and syringed the liquid to him orally and suddenly I panicked because at that point he went into convulsions gasping his last breaths I administered immediately some water and soothed his throat because I may have caused him to choke and gave him water… He somewhat gained his breathing but started convulsing again screaming until he died at 5:pm August 17th 2008

I will never buy another product over the shelf from sargeants or any other manufacture of these common toxic chemicals…It virtually did little or nothing with the fleas but ultimately killed my Himalayans consecutively….by putting trust in a well known manufacture unknown to myself of a deadly product is not only inhumane on their part but also criminal and negligent of not producing a fail safe product and high in toxicity…shame on you Hartz/Sargeant and whoever else manufactures this product for purely profit and not the wellbeing of the animal community….I find it utterly disgusting and heart wrenching…and of course I live alone without my little  defenseless friends…If I had the money i’d spend millions to sue your #%^^^just to take away your right to sell this deadly product…If there is a petition out there I want to be on it and possibly be part of any lawsuit against these firms…They know they are getting away with murder and openly admit there’s a problem with their products as one person put it [email protected] They haven’t got a call from me but when I find the number i definitely will call …As well I’m calling Customer Relations at Canadian Tire where I bought the product….and attempt to have it removed…

My cat was very sick.

I used Hartz One spot treatment that I bought at Wallgreens on my cat.  She became very sick.  She was acting like she was very scared. I noticed she wasn’t cleaning herself and she didn’t have any energy. I then noticed she wasn’t eating. I didn’t even think of the Flea treatment at first, I thought she just had a regular illness. After two full days of this I started getting concerned and started thinking about calling a Vet. I then realized the Flea treatment I had given her and I immediately gave her a bath. Almost right after the bath she seemed back to normal. She wasn’t scared and she was very hungry and started cleaning herself again. I wonder how many pets get sick from this Harts product and how many die?

My Angel is dying

I did what I thought was good for my baby girl,Angel, by buying HARTZ flea drops and flea collar.We gave her a bath,and put both on when she was dried.Imagine my shock today,when we took her into the vet to hear we were doing more harm than good!She is soooo anemic now because of the fleas the product was supposed to be protecting her from are attacking her more and her life is now in peril! How are they still allowed to sell this CRAP that only endangers the little lives of those that we love so much?!? I guess the moral to the story is don’t buy from the grocery store for a quick fix….go straight to your vet for solutions.I may regret my error in judgement the rest of my life if my baby doesn’t get better!

I used Hartz Ultra Guard Flea and Tick Drops for Dogs….

I just used Hartz Ultra Guard Flea and Tick Drops on my dog 3 days ago and I haven’t noticed any problems with him, but I am afraid that he may develop something from the use of this product. I just happened upon this site because I typed in flea drops looking for information about Advantage Flea Drops. I had NO idea that Hartz was such an awful product until I read some of the stories. Now I’m afraid that something could happen to him because I put the drops on him. It has been three days and there have been no reactions, but I’m not sure how long it takes for reactions to show up? If anyone has any ideas how long it would take for a reaction to occur, please let me know. Thank you.

This will be the last time I ever use a product made by Hartz!


Two weeks ago my elderly mom and step dad had 5 wonderful, healthy cats who they considered their “family” and called them the “kids”.  They ended up with fleas, and someone bought them the flea collars and some Hartz spray for cats.  I live 500 miles away, or would have told them NEVER to put any HARTZ on their pets.  Their cats started to get ill and they do not drive and could not find anyone to get them to the vet.  Four died in 2 1/2 days, and I drove down and got the last one to an emergency hospital and they said the poor thing would have been dead by morning.  The vets at the hosptial TOLD me to sue Hartz.  They gave me back the product and said they encourage everyone to sue HARTZ every time this happens.  My parents are devasted and I am going to do all I can to let other people know how horrible these products are.  Even if they reimburse the $900 for the cat that survived and the $1064 for the cremations, it will never bring back these wonderful animals. Some man on the phone today wanted to know if I wanted the money back for the product!!!   Sick………………………………………………………….

Hartz Ultra Guard flea spray for home

I used this spray as per the generic directions on the bottle and I had seiz and muscle spasms two hours after I used this product.The seizures continued throughout the night and when I saw my neurologist she got together with poison control and the partial diagnosis was poisoning. I am a person and this product did this to me. I am still suffering from mild seizure activity one week later. I have never had any seizure or neuro problems in my life. I need a good lawyer and I live in North Florida. Help!
